Abstract

The invention relates to a granulating auxiliary agent for preparing large-particle potassium sulfate or ammonium chloride. The granulating auxiliary agent comprises the components by mass percent: 40-60% of silica gel, 10-20% of aluminum chloride, 10-20% of aluminum sulfate and 10-20% of magnesium sulfate, wherein the sum of the mass percents of the components is 100%. The granulating auxiliary agent can be prepared by evenly mixing and stirring the silica gel, aluminum chloride, aluminum sulfate and magnesium sulfate. Compared with the existing granular ammonium chloride or potassium sulfate production process, the process for preparing the large-particle potassium sulfate or ammonium chloride fertilizer by using the granulating agent provided by the invention has the advantages that (1) the production process is simple; (2) the granulating agent is suitable for multiple granulating ways such as a drum granulator or a disc granulator; (3) the prepared fertilizer is high in granule strength and has the average crushing pressure of 20-40N; (4) compared with the yield of extrusion granulating, the yield using the granulating agent is higher; and (5) the granulating agent is low in cost.

Description

technical field [0001] The present invention relates to a kind of granulating agent that is used to prepare large particle potassium sulfate or ammonium chloride, after using this granulating agent, can utilize granulation equipment to produce large particle ammonium chloride, potassium sulfate, disc or drum, It replaces the existing extrusion method to produce granular ammonium chloride and granular potassium sulfate. Background technique [0002] Potassium sulfate and ammonium chloride, as a high-nutrient elemental potassium fertilizer and elemental nitrogen fertilizer, are indispensable fertilizer varieties for crops. In the past 20 years, the world's large granular urea, ammonium phosphate, compound fertilizer, granular potassium fertilizer, granular ammonium chloride and other products have developed rapidly. Fertilizer granulation is one of the development trends of chemical fertilizers today. [0003] 1. Granular fertilizer is the development trend of chemical ferti...
